The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.

Each DW DMA controller channel can be synthesized with different
parameters like maximum burst-length, multi-block support, maximum data
width, etc. Most of these parameters determine the DW DMAC channels
performance in its own aspect. On the other hand these parameters can
be implicitly responsible for the channels performance degradation
(for instance multi-block support is a very useful feature, but having
it disabled during the DW DMAC synthesize will provide a more optimized
core). Since DMA slave devices may have critical dependency on the DMA
engine performance, let's provide a way for the slave devices to have
the DMA-channels allocated from a pool of the channels, which according
to the system engineer fulfill their performance requirements.
The pool is determined by a mask optionally specified in the fifth
DMA-cell of the DMA DT-property. If the fifth cell is omitted from the
phandle arguments or the mask is zero, then the allocation will be
performed from a set of all channels provided by the DMA controller.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces the Synopsis
Designware DMA controller legacy bare text bindings with YAML file.
The only required prorties are "compatible", "reg", "#dma-cells" and
"interrupts", which will be used by the driver to correctly find the
controller memory region and handle its events. The rest of the properties
are optional, since in case if either "dma-channels" or "dma-masters" isn't
specified, the driver will attempt to auto-detect the IP core
configuration.
